[PATCH 5.10 160/199] selftests/powerpc: Fix exit status of pkey tests

[Greg Kroah-Hartman]

From: Sandipan Das <sandipan@xxxxxxxxxxxxx>

commit 92a5e1fdb286851d5bd0eb966b8d075be27cf5ee upstream.

Since main() does not return a value explicitly, the
return values from FAIL_IF() conditions are ignored
and the tests can still pass irrespective of failures.
This makes sure that we always explicitly return the
correct test exit status.

Fixes: 1addb6444791 ("selftests/powerpc: Add test for execute-disabled pkeys")
Fixes: c27f2fd1705a ("selftests/powerpc: Add test for pkey siginfo verification")
